浮箱是张力腿平台主体结构的组成部分之一，它承受着由平台甲板和立柱传递来的总体载荷以及局部静水载荷。不同的浮箱结构型式会对荷载路径和受力大小产生影响，不同的设计需求会带来不同的结构型式设计。本文介绍TLP平台浮箱框架的典型结构型式以及基于有限元的强度分析方法，并通过浮箱横向框架有支柱和无支柱2种不同型式的浮箱框架结构案例分析予以阐述。
Pontoon bulkhead structures of Tension Leg Platforms (TLPs) are designed to withstand both local and global loads. The pontoon configuration will affect the load path and stress level such that different design tasks may result in different configurations. This paper introduced general configurations of TLP pontoon structures and elaborates the structural strength analysis method based on the finite element method by giving two engineering cases with different structural configurations, i.e. transverse frames with stanchions and without stanchions.
